It only needs +/-5 and +/-12 volts (and you may be able to
drop one or more of those, many devices only use a couple),
so you could do it with 8 batteries, or if you wished you
could use a DC-DC converter to raise the voltage from
fewer batteries.
Either way you're going to be pulling quite a bit of power
from the batteries. CDROMs are not designed to be very
power efficent, as they are intended to be connected to
an unlimited supply (ie, the wall socket). A laptop
CDROM might be better, and may have a little better
shock resistance too, not to mention being smaller.
Most battery manufacturers websites have at least Ah
ratings for their batteries, and some even have discharge
curves. Check your CDROM for its power requirments
(usually printed on the drive), and calculate how
fast it would eat batteries.
